Specification of Letters Patent.

Patented March 19, 1907.

Application tiled October 14,1905. Serial No. 282.786.

.Be it known that l, Entrar D. Birnxns, a citizen ot the United States, residing` at Traverse (,ity, in the county7 ol' Grand .Traverse and State ot Michigan, have invented a new and useful Yhadiator Vent Attachment, oi which the following is a specilication.

rthis invention relates more particolari)Y to means tor permitting the escape oi air from a radiator when steam is turned into the same.

(lne oithe principal objects is to provide novel means ot a simple nature that is read il y applicable to any well-known type oi" radiator, said means permitting the tree escape ot air from and preventing its ingress into the rad iator when a partial vacuum is termed therein.

Another object is to provide muftling means which permit the escape of air without noise, and, iurthern'iore, to provide an attachment which may be applied to an ordinary vent, said attachment having means whereby the valve mechanism ol such vent may be conveniently adjusted without the necessity ot removing the attachment.

The preferred embodiment o'll the invention is illustrated in the accompaigiying drawings, wherein- YFigure 1. is a side elevation ot the attachment applied to a radiator. Fig. 2 is a longitudinal sectional view through the same. ltig. 3 is a cross-sectional view through the casing.

Sin'iilai. ielorcnce-numerals designate corresjionding parts in all the iigures oil the drawings.

A portion of a radiator is shown in the accompanying drawings and is designated 4, said radiator being provided with a wellknown torni et vent device 5, which includes an upstanding outlet-stein 6, having an adjusting-screw 7 threaded. thereinto. This screw is provided with the usual outlet-channel 7, operating in a manner well understood to those skilled in the art. The structure inV this particular is not important and may be varied as desired.

The attachment forming the subjectmatter oit this invention is constructed as iollows: A nipple 8, substantially in the torni oi a `1"-coupling, has one end S) interiorly threaded to screw upon the stem o, the opposite end being provided with a cap 10, in` which is rotatably mounted an actuziiting screw-driver stem 11, said. stem extending longitudinally through the nipple and Vhaving a head 12 that is adapted to engage in the slot ot the adj Listing-screw 7. An actuatingwheel 13 is located on the exterior end ot the stein tor turning the same. 'llo the intermedia te boss 1-1 oi the nipple is secured the upper end oi' a downw: illy-extending conduit 15, having` an. ollset lower end 16 threadcd into a coupling 17, said. coupling Vtlaring toward its outer end. Anv upstanding cylindrical casing 1S is screwed upon. the out ar end ol? the coupling 17 and carries a cap 19 at itsupper end, which cap is provided with an outlet 20. A perforated partition 21 extends across the casing 1S between its ends, said partition defining the top ot a water-chan'iber 22. A valve-seat 23, carried by and preterably forming a part ot the upper end ol the coupling 17, constitutes the bottom of the casing. A valve 21.1, preferably, though not necessarily ot the ball type, is located in the water-chamber 2") and normally rests upon the valve-seat 23, said valve thus opening outwardly or upwardl The casing 1S above the partition is substantially lilled with inujtlling means, said. means comprising a body 25 ot any suitable porous material through which air can pass.

ln use the device is attached to the outlet oiE the ordinary radiator -vent, as shown. Consequently it will be seen that air escaping through said vent must pass through the conduit 15 by the valve 24 through the muffler. finally escaping at the orifice 20. rlhe outward passage ol: the air opens the valve, and the noise or said escaping air is prevented by the muiiler. it, however, a partial vacuum should be formed in the radiator, the valve 24 will seat itselt and thusprohibit theingress of air. The device when in place will not interiere with the adjustment of the valve mechanism ot the vent 5, tor the actuatingstem 1.1. aftiords convenient means tor adjusting the screw 7. Consequently it is not necessary to remove the device in order to adjust said screw.

l? rom the foregoing .it is thought that the construction, operation, and many advantages ot the herein-described invention will be apparent to those skilled in the art without iurther description, and it will be understood that various changes in the size, shape, proportion, and minor details oi construction may lbe resorted to without departingl from the spirit or safri'liring any of the advantages ot the invention.. For instance, the particular type of valve employed is not essential, and that illustrated may be substituted by lOO anv other vvell-lnovvn form. the material of vvliith the strueted ma v lve an vthing` lo'r the purpose.
